To all whom i may concern:

Be it known that we, Lrm'roN E. RENNEY and WILLIAM J. Pannen, citizens of the 'United States, residing 1n the city and to which it is attached.

' part of the load means it is' a well known fact that more time and labor are required to properly place heavy merchandise or material on the bed of -a truck, or car platform, in proper load formation than is required to Abring the goods to the side of the same for loading. For eX- ample, in the loadin of blocks of stone or heavy castings, mach nery and the like, it is necessary to pinch, or roll them in proper.

load formations aft/er they have been lifted to the bed of the truck, or common carrier. This process-is expensive in both time and labor. The process of unloading all or a the same loss of time and labor as the loading, and not only this, the merchandise is often damaged through rough handlin thus ent-ailing additional loss on either t e owners or transporters of the freight.

The object of our invention is to overcome the above objectionable features by a simple and comparatively inexpensive device which may be attached to the frame, or bed of any truck or common carrier.

For a clear comprehension of the construction and operation of our invention, reference should be had tothe accompanying drawings in which Figure 1, isa side elevation in perspective of the device secured to the vehicle frame. The center is broken open to indicate the indeterminate length of the movable load platform. The sides 4are broken away showing the surface of the same. Fig. 2, is a cross-section of the same showlng the relative position of the roller supports inthelinks of the sprocket chains connecting the iiexible ooring of the load platform. This ing platform of a car or warehouse,

view also shows the center or auxiliary members for strengthening the center of the movableplatform, and a means for securing the device to the frame of a motortruck, or common carrier.

The numeral 1 is used to designate 'the `frame of a motor driven truck, or common carrier of any suitable `type for the transportation of heavy merchandise or material.

2 is the frame on which the mechanism is mounted.

38, are the central supporting members with the cross ties 4, 4.

5, 5, are the brackets by which the device is securedl to the frame of the truck, or common carrier.

6, 6, are overlapping corrugated or plain, nected by means of the sprocket chain 7 each link of which is provided with the roller or anti-friction wheel 8. The sprocket yshafts 9 and 10 are mounted -in planks or cleats,

suitable bearings 11 and 12. These shafts are provided with the sprockets 11 and 12. The ends of said sprocket shafts are squared for applying the power to operate the device. The rear bearings 12 arev provided with the extension arms 13, the ends of which vform a bearing in which the guard roller -14 is mounted.

1-5, 15 are the detachable movable sides, with the supporting stanchions 16, 16, in the lower end of which are the hooked bearings 17, 17. The dotted lines-"X-X (Fig. 2), show the relative'position of the sides when released to facilitate the operation of unloading.

18 is a turnbuckle and rod for4 securing the sides in position to protect and carry the load.

19 is the front end gate with its ing brackets 20, 20.

The operation of our device is as follows: The motor truck, or common carrier, with our device attached is brought to the loadand the merchandise or material is hoisted onto ythe platform of the motor truck in the ordinary manner. When placed in load position on the tail of the truck', the operator applies power to either of the sprocket shafts, rotating the same, and, by this means, causes the endless flexible load platform to move forward a suitable distance, carrying the'articles of merchandise, or material with it. This movement brings into supportwhich are fleXibly con structed of place at the tail of the truck room for the next articles to be loaded. As soon as they are in place the operation is repeated, and so on until the first articles of merchandise, or material, loaded have reached the front end gate, thus filling the bed and constituting a load. To unload the vehicle, the above operation is reversed, and by this means either the entire load may be dumped, or any' part thereof. To prevent unnecessary friction by reason of the sides coming in contact with the load during the movement thereof the detachable movable stanchions are provided.4 By this means the sides are released (indicated by dotted lines X-X Fig. 2), or removed entirely during the process of loading or `unloading a motor truck, or common carrier, equipped with our device.

It will be readily seen that our invention a practical labor and .time Savin device. We do not wish to be understood v as confining ourselves to the precise construction shown herein, buty wish to availv ourselves of any modifications that maynproperly fall within the scope of our invention.

Having described our invention, what we claim and desire to secure by Letters Patent 1s A l. In combination in a motor truck comprising a frame composed of beams disposed longitudinally of the vehicle and joined together by transverse members, a secondary suplporting frame similarly conongitudnal and transverse members, said secondary frame being suitably elevated from said vehicle frame and supported therefrom by side brackets, a flexible endless carrier adapted to pass over and around the secondary frame to form a movable load platform A'for the vehicle, detachable side boards supported on said supporting frame, a permanent front end gate supported from the vehicle frame by arcsha ed brackets, and a guard roller sup orted y a rbracket. from the rear end of) the said roller being disposed 1n alinement with the upper Hoor level of the vehicle, substantially as'described.

2. In combination in a motor truck, a suitable frame, a flexible .endless carrier, and a guard roller 14 arranged at one end of the truck in proximity to' the surface of the carrier as it travels around its support. p

3. In combination in a motor truck comprising a frame, an endless carrier, a front end portion, and arc-shaped brackets 'supporting the same from the frame and-permitting free, uninterrupted movement of the endless carrier, scribed.

In testimony whereof we aix our signatures in presence of two witnesses.
